One of the best HVAC supply houses in Denver. Shane, Timmy, Christian, you name it. You can't go wrong with any of their staff. Super professional and they always get me what I need. Would recommend them to anyone!

Shane at the counter, he is 100% my go-to guy. He asks detailed info to double check and cross reference parts to guarantee you get what you need! If you have a choice find him for help!

I’ve been coming to Johnstone supply for the last five and a half years. They really are your best bet for trying to locate hard to find parts, finding a good price, and for even a good time! I truly enjoy coming here and get happy to do so. The entire team is extremely helpful. There’s guys with decades of combined experience from guys like tj josh and Jeff. Then you got some of the newer guys like Shane and Sonny who work relentlessly to ensure you have a great experience, and get the correct parts. Much love to Johnstone 10/10 would Johnstone again.

I have been coming to Johnstone for the last 5+ years now and I want to say that I have never had a bad experience. Although wait times to get to the counter can be high, I have never had a bad experience when working with any individual at the counter. My most recent experience involved Shane P. and he went above any beyond to help me find everything I needed while shopping at Johnstone. From here on out, Shane is going to be my go to individual at the counter based on the experiences I have had with him!

I just wanted to take some time to commend this supply house as a whole! Definitely without doubt, the best parts warehouse in town. Specifically Josh and Shane. Every time I have a job coming up they go out of their way to make sure I have all the proper fittings and electrical components to complete the job and everything I need to create a properly commissioned installation. Also on a day to day business, this supply house has been so supportive of my company, they take their job seriously and make sure I have the parts I need, they are they parts specialists for any brand of equipment I touch.

I generally like this supply house, most of the staff are friendly and helpful, and I’ve spent tens of thousands here over time. However, my experiences with one employee, Shane Palacios, have consistently been negative. In my visits, he often seems upset or irritated, even when speaking with customers, and my employees have mentioned similar experiences. It feels unprofessional, and I hope management can address it so the overall service stays as good as the rest of the team.

Was in there yesterday for a basic steam radiator valve inch and a quarter and they told me it was 107.00 each. I can get decent ones online for 40 each easy. The idea that they can mark things up so much is borderline criminal

Johnstone is singlehandedly the industry standard for product lines, product knowledge, HVAC classes, customer service, and simply how they do things. From the locker system to online ordering, they have not only set the bar high for everyone else, but they've created the bar in which every other supply house strives to reach. You know you're doing something right when competitors recommend you to Johnstone anytime they don’t carry what you're looking for.
I've done business with Johnstone for almost 4 years, and they have been great to work with from day one. From the counter guys, like Christian Alonzo, Anders, Curtis, Terry, Sal, Josh, Eric, Glen, Doron, Shane, Jeff, TJ, and Tim to the guys in Will Call like Jason, they have all been phenomenal to work with and incredibly helpful! Even the folks upstairs on the phones like Karen, Janelle, and Marcia. Just awesome! There have been times when I've simply called Johnstone to ask a question about compatibility or functionality on a product and had no intentions of buying. Yet they were there to help as always!
Johnstone is by no means going to be the cheapest option, though at times they will be, but when you work with Johnstone, there is a sense of quality, knowledge and customer service that you simply don't find at most supply houses.

Sal is hands down the best, and Jeff is a razor shave close second. But they have SOO many Great staff members .
I think the only part that matters in this type of place is the way they handle problems. Because the price is the price. The products are the same. The only time you get to really see a business shine is when there's a problem.
Now, there's definitely not a lot of problems with this place. Anybody who uses a supplier like this knows that problems happen. Every time I come here with a problem, I always leave happier than when I walked in, and by no small measure.
The extra miles the good times the jokes and laughing behavior but not taking things too seriously, but still keeping it business.All of these things are the things that add up to making a place, a great place to visit.
I hate having to go to Home Depot during my work day because it just takes so much time.
But A trip to johnstone as always a mixed emotion, because i'm usually not in denver, so it's about to be a long drive, but I know it's gonna be a great time at the shop ?
This post was made after a trip to exchange parts after being given the wrong one..... clearly I'm not sore about it
Thanks Guys
